User Guidelines This command can be used to configure IPv4 BGP neighbors (BGP Router Configuration mode) as well as IPv6 BGP neighbors (IPv6 Address Family Configuration mode). Use the limit keyword and max-number argument to define the global maximum number of IPv4 BGP dynamic neighbors that can be created. BGP dynamic neighbors are configured using a range of IP addresses. Each range can be configured as a subnet IP address. After a subnet range is configured for a BGP peer group, and a TCP session is initiated by the neighbor for an IP address in the subnet range, a new BGP neighbor is dynamically configured on the local switch. Dynamically created neighbors are not displayed in the running-config. It is acceptable that the template peer name is not specified. In this case, all dynamic neighbors are created with the default parameters. The template peer name can be assigned/changed for a listen range at any time. The limit on the total number of both IPv4 and IPv6 listen range groups is 10. Command History Introduced in version 6.3.0.1 firmware. Example The following example shows how to create an IPv4 listen range with a template to be inherited with dynamically created BGP neighbors: console#configure console(config)# router bgp 100 console(config-router)#bgp listen limit 10 console(config-router)#bgp listen range 10.12.0.0/16 console(config-router)#bgp listen range 10.27.0.0/16 inherit peer ABC bgp log-neighbor-changes Use the bgp log-neighbor-changes command to enable logging of adjacency state changes.
